MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed February 7, 1914. Serial No. 817,261.

To all whom it may 0071mm Be it known that I, RALPH MARINO, a citi- Zen of the United States, residing at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented new and useful Improvements in l Iusic-Leaf Turners, of which the followingis a specification.

This invention relates to music leaf turners; and it has for its primary object the provision of a swinging turning arm which may be supported from a portable music rack and which may be directly operated by foot power and adjusted so as to turn the leaf at the required moment.

A further object of the invention is the provision of means for facilitating the operation of re-setting the turning arm.

\Vith these and other objects in view, the invention consists of certain novel features of construction, combination and arrange ment of parts, as will be hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a front view of the device, showing the application thereof to a portable music rack; Fig. 2 is a rear view thereof; Fig. 3 is a side view on an enlarged scale of the turning arm and the latch mechanism, showing parts in section; Fig. 1 is a view similar to Fig. 8, showing the re-setting means in a position to return the turning arm to its initial position; Fig. 5 is a section on line 55 of Fig. 1; Fig. 6 is a section on line 6-6 of Fig. 1; and Fig. 7 is a section on line 77 of Fig. 1.

Vhile the turning mechanism is designed for application to any desired form of music rack or support it is described that it is principally intended for use upon such portable music racks as the one shown at 1. This rack is of the design generally employed by orchestra musicians, and it preferably includes a supporting base 2 having telescopic sections 3 and 4, the former having foldable supporting legs 5 which may be spread or adjusted so as to hold the rack in proper set up position. The companion telescopic sections 3 and 1- may be adjusted with relation to each other and in a vertical plane so as to cause the supporting frame of the rack to be suspended at any desired height. The base 2 is split at 2 and adjusted thereon is a clamping nut 2 whereby it may be adjusted to cause the divided parts of the split end 2- to engage in clamping like manner against the next section of the stand.

The upper section 4: of the stand is provided with a main rack 6, on whiclfthe music sheets may be arranged in the usual manner. The intermediate vertical bar 7 of the rack is provided with a casing 8, and mounted to rotate in said casing is a shaft on which the turning arm 10 is secured. This arm is provided with a drum portion 11 at its immediate connection with the shaft and to one side of the drum portion the arm 10 is provided with a passage 12. Around the drum is wrapped a flexible connection such as a cord 13, one end of which is secured to the drum at let, and the other end is eX- tended over to an attaching hook 15 on the return mechanism 16. The shaft 9 is embraced by a spring 17, one end of which being secured to the shaft and the other end 18 being secured to a suitable portion of the casing 8 so that under the action of the spring the turning arm 10 is made to move in one direction. The said turning arm 10 is of course located at the front of the frame 6 and positioned thereon so that it may be operatively associated with the leaf of the music to be turned and for this reason it is provided with any suitable well known form of fastening clamps 19, 19, as shown in Figs. 1 and The vertical bar 20 of the frame 6 is provided with a. pivoted hook 21 having an effective holding portion 22, which is normally engaged with the free end of the turning arm 10, so as to hold said arm against the action of the turning spring 17. The said hook is provided with a tail 23, which extends through an elongated slot 24 in the vertical branch 25 of releasing means 26. Said means is constructed from a single length of wire preferably, which is provided beyond the portion 25 with a relatively long branch 27 and from the latter the wire is extended in a downward direction, as at 28, and it is connected by telescopic members 29 and 30 with the stand 1. Guides 31 on the stand 1 are arranged so as to freely receive the sections 29 and 30 in their vertical movements. The lower section 30 is operatively connected with a hook actuated treadle 31 pivoted in a bracket 32, which may form a part of the lower portion of the section 2 of the mentioned stand 1. Beneath the foot engaging end of the treadle is a spring 33 under the ofiice of which the treadle is normally held in an active position. In other words, the foot engaging end thereof is held elevated and in a position so that it may be properly depressed by the foot when it is desired to release the end 22 of the hook 21 from the turning arm 10. Through the arrangement previously referred to, it is seen that when the treadle is depressed against the action of the spring 33 the member 26 will be raised and the lower end of the slot; 24 will be brought to engage against the tail 23 of the hook 21. The latter is then operated to release the portion 22 from the turning arm and the said arm is then free to move in one direction under the action of the turning spring 1'1". The foot of the operator is held on the pedal 31 until it is de.-.

sired to re-arrange thesheet or to return the same. At this time it is mentioned that the spring 33 has a pressure which is greater than the turning power of the spring 17 so that when the treadle is released the parts will be operated to cause the arm 10 to again engage with the etlectiveend 22 of the. hook 21. Hence, the provision of the returning mechanism 16 and the spring 33. The returning mechanism consists of an arm 3% pivoted at 35 to the vertical portion 28 of the member 26 and at the opposite end the mentioned rod Bl is provided with a, head 36 having a central groove 38 and end flanges 39, 39,. The grooved portion of the head- 36 is accommodated in the slot 0 at one side of the casing 8, while the flanges 39, 39 are respectively engaged against the opaction of the spring 33, it is evident that the connection 13 will. tend to partly unwind from the drum 7 and thereby cause the drum to revolve and the arm 10 thereof to be rese t.

I claim:

In a leaf turner, a turning arm, a spring for turning said arm .in one direction, a hook for holding said arm against the action of said spring, a slidably mounted rod for operating said hook, a casing, a link, having one extremity pivotally connected to said rod, and its remaining extremity slidably mounted in said casing so as to travel in a horizontal direction, a drum secured to one end of said arm, and a flexible element connecting one extremity of said; link to said drum.

In testimony whereof I atfix my signature in presence of two witnesses.
